Innovate Air Fuel Gauge/Diablo Tuner

I recently had a supercharger installed on my 2014 Jeep SRT. I'm having an issue with the tuning though due to the air fuel gauge reading wrong. After the air fuel gauge is installed there are three wires remaining Brown, Yellow, White. Diablo makes an analog cable that connects to the air fuel gauge with 4 wires Red, Green, Black, and White. The problem is neither Innovate nor Diablo know which wires to connect. Diablo sent me a link to a forum where someone supposedly figured it out, but since trying that option my air fuel gauge is reading in the 10's, I know the reading is wrong. Can anyone assist me with this?

Re: Innovate Air Fuel Gauge/Diablo Tuner

Red wire = Tip, Green wire = second ring. black and white wires = Ground


Connect the red wire from the DS analog wire to the yellow wire on the MTX-L. Connect the black wire on the DS analog cable to ground, preferably they all use the same ground (MTX-L, DS cable, relay if using one).


The Brown wire on the MTX-L is not used.




Also, make sure you follow the calibration instructions included with the MTX-L.




2.4 Sensor Calibration


Once the unit has been wired and a suitable location has been found for both the gaugeand the sensor it is time to do the sensor calibration. Innovate Motorsports’‘Direct Digital’ wideband measurement principal allows you to calibrate thesensor to compensate for sensor wear. This procedure takes just a few momentsand it will ensure the most accurate readings throughout the oxygen sensor’slife. This procedure is required anytime a NEW oxygen sensor is installed.


Thecalibration procedure requires that the oxygen sensor be in free air,this means removed from the exhaust system completely.


1. With thesensor disconnected, apply power to the MTX-L. When power is applied, all three digits willlight up and the needle bar will sweep once through all LEDs. Then the statuslight will turn red and the numeric display will read “E2”. This is an errorcode, indicating that no sensor is detected. Leave unit powered on for minimum30 seconds.


2. Powerdown the MTX-L and attach the oxygen sensor using the cable provided. Whenmaking these connections, make sure they are fully seated and locked. Again,make sure that the sensor is in free air (not in the exhaust).


3. Powerup the MTX-L. Again, the displayshould ‘sweep’, but instead of an error, the display will display “Htr”. Thisindicates that the sensor is being heated up to operating temperature. After30-60 seconds, the display will switch from “Htr” to “CAL”, indicating that thesensor is being calibrated. A few seconds later, your MTX-L will begindisplaying AFR. Since the sensor is in free air, the gauge will default to theupper limit of 22.4.


Thecalibration procedure has completed and the system is now ready for use.

Thank you! I'll have to try this! It's been a huge headache.

When you say red wire = tip and green wire = second ring, what do you mean?

Re: Innovate Air Fuel Gauge/Diablo Tuner

I probably should've mentioned it's an Innovate LC-2 air fuel gauge.

Re: Innovate Air Fuel Gauge/Diablo Tuner

The analog cable for the DS has 2 inputs. The red and black wires are one input, the green and white wires are the second input. You should only need one input wired up. I would use black and red. Black will be to ground, Red wire will go to the Yellow wire on the LC-2.

Does that clear it up?
